Neuromorphic computer chips of the future could be made from honey

Engineers at Washington State University have been able to create a functioning neuromorphic memristor from honey. In their opinion, this opens up prospects for the creation of new computer chips – sustainable, biodegradable and extremely powerful.

A memristor is a passive component (resistor) that is capable of storing data in much the same way as the human brain does. The honey memristor, created by scientists, is about the thickness of a human hair. The developers believe that if it is made even 1000 times thinner, then it will be possible to create neuromorphic computers.


To create a memristor, scientists processed bee honey into a solid form, which was then placed between two metal electrodes – the result was a semblance of a human synapse. The test was successful: the new development successfully imitated the activity of nerve endings, that is, turned on and off at a speed of 100 to 500 nanoseconds. The scientists also reported that the honey memristor is completely biodegradable.

“Honey does not spoil. It has a very low moisture concentration, so bacteria cannot survive in it. This means that these computer chips will be stable and reliable for a very long time. When we want to dispose of a device that uses honey computer chips, we can easily dissolve them in water. Due to these special properties, honey is very useful for creating renewable and biodegradable neuromorphic systems,” said Feng Zhao, assistant professor in the School of Engineering and Computer Science at Washington State University.

The team published their findings in the Journal of Physics D: Applied Physics.
